In this paper the information about the biological monitoring carried out in Okhchuchay and Basitchay located in the Zangilan region, and algoflora saprophy of these rivers were reflected. As a result of the research, it was determined that species belonging to the oligosaprobic, mesosaprobic and polysaprobic zones are more often observed among the mass samples. The upper reaches of Okhchuchay and Basitchay are considered to be the most polluted zone, where the common species are called polysaprobic species. The aim of the work is a comprehensive study of the ecological condition of river basins subject to high anthropogenic influences, assessment of saprobity and protection of the water body as a unique biosystem.
